Specification forming part of Letters Patent No. 150.9111. dated May 19, 1874; application filed October 9, 1873.

To all whom it may concern:

Be it known that I, WILLIAM HENRY OROCKER, of Boston, `in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in the Manufacture of Mats or Squeezers used in Pressing Linseed-Oil and other Fats and Liquids; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the figures and letters ot' reference marked thereon.

The peculiarity of this invention consists in the use of metallic wire, either alone or in combination with hair, wool, cot-ton, hemp, or other 4suitable material, and its operation is as follows, viz: The wire, being woven through and through the mat, both'ways, receives the pressure and sustains the hair or other material, thereby preserving its strength and elasticity much longer, and insuring the following advantages, viz: lIncreased durability in the mats, and a great economy in keeping the same in repair; less expansion, consequently less friction or wear on the woolen (or other) bag containing the material operated upon; greater ease of manipulation to the Workman from their (the matsyrigidity and ability to support themselves when loaded for the press; and an increased yield of the desired product.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction.

Preferably I form a rope of hair and wire in either of the following or other ways: First, (Figure l in the drawing,) I form a center strand of one or more threads of wire, W, Fig. 1, the other strands being made of hair, and lay up the rope in the usual way; second, (Fig. 2 in the drawing,) I spin the hair around one or more threads ot' wire, W, Fig. 2, and lay up lthe threads and strands thus formed in the usual manner.

The combination rope so made I then Weave on a suitable frame, Fig. 3, either by itself, or alternately with one or more strands ot' naked wire, W, Fig. 3, and proceed with the manufacture in any ot' the usual ways.

f Fig. 4 in the drawing represents the mat or squeezer finished, excepting the leather cover which itis customary to apply before using, the two middle ribs, forming the hinge, being woven ot' hair rope without wire, that it may
